react-rewards

❇️ GPU-rendered: WebGL2, with a Canvas 2D fallback

🌲 Tree-shakeable: about 7.5 kB gzipped for useReward and confetti

🕵️ Built with TypeScript

⏱️ Frame-rate independent, and quiet for people who prefer reduced motion

React-rewards lets you add micro-interactions to your app, and rewards users with the rain of confetti, emoji, balloons or fireworks, or a pop of stars, in seconds. Firing confetti all over the page may seem like a questionable idea, but keep in mind that rewarding users for their actions is not. If a huge cloud of smiling emoji doesn’t fit your application well, try changing the physics config to make it more subtle.

You can read more on the subject of micro-interactions in my blog post - https://www.thedevelobear.com/post/microinteractions/

Docs and demo

thedevelobear.github.io/react-rewards has every effect live, with its settings and the code for what you pick, and the docs:

• Getting started
• useReward: its settings, burst options and return value
• fire: effects without React
• Renderers: WebGL2, Canvas 2D and setRenderer
• Custom effects with defineEffect
• Server rendering
• Upgrading from v2

Installation

pnpm add react-rewards
# or
npm install react-rewards
# or
yarn add react-rewards

React 18 or later. The package is ESM only.

Usage

Give useReward a ref to the element a reward starts from, and an effect. Each call to reward() fires a burst from the centre of that element.

import { useRef } from 'react';
import { confetti, useReward } from 'react-rewards';

export const RewardButton = () => {
  const ref = useRef<HTMLButtonElement>(null);
  const { reward, isAnimating } = useReward(ref, confetti);

  return (
    <button ref={ref} type="button" => reward()}>
      {isAnimating ? 'Yay!' : 'Reward me'}
    </button>
  );
};

The effects are confetti, emoji, balloon, firework and pop, and each has its settings on its page of the docs.

Support

• React 18 or later.
• Chrome and Edge 87, Firefox 79, and Safari 14.1 (iOS 14.5), or later. Bursts draw with WebGL2 where it’s available, and with Canvas 2D elsewhere.
• The package can be imported on the server: nothing touches window until a burst fires.
• Only the latest major version gets fixes.

Versions follow semver. A patch fixes something. A minor adds something, or changes how a built-in effect looks, and the changelog gives the old settings to keep the old look. A major can break your code, and whatever it removes is deprecated in a minor first.
